DUST AND DRAFT SHIELD.

To all whom it may concern:

Be it known that I, FRANCES J AEGER MOONEY, a citizen of the UnitedStates, residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a certain new and useful Improvement in Dustand Draft Shields, of which the following is a specification.

My invention relates to a new and useful improvement in dust and draftshields, and has for its object to provide an exceedingly simple andeffective device of this character which may be placed beneath a door toprevent dust or a draft passing underneath the same.

Other objects of my invention are to provide a shield which may beadjusted to fit beneath doors of different widths and one which willadjust itself to the size of opening between the door and the sill.

IVith these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may under stand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which Figure l is aperspective view of one end of a shield made in accordance with myimprovement. Fig. 2, a longitudinal sectional view thereof. Fig. 3, asimilar view showing it applied to a door. Fig. 3 a sectionalperspective showing sectional strengthening strips. Fig. 4. aperspective view of a portion of a modified form of shield. Fig. 5, aperspective view of the preferred form of my invention. Fig. 6, a crosssection of Fig. 5.

In carrying out my invention as here em bodied, A represents the body ofthe shield preferably formed of metal, having a back portion B and abase C bent at right angles to one another, the front edge of the baseis turned back upon itself as indicated by D, forming a chamber E, inwhich the forward edge of the swinging plate F is adapted to rest. Inthis chamber E is secured the lower end of the flat spring G by means ofthe rivet H which passes through the base C and its turned up front edgeD. The outer portion of this spring is fastened to the Specification ofLetters Patent.

swinging plate F by a rivet I or its equivalent. The tension of thisspring will nor; mally hold the swinging plate at about the angle shownin Fig. 2. The upper edge of the back B is turned down upon itself asindicated by J until it rests in proximity to the inner surface of theback B leaving a space K between said back and its turned over edge,which acts as a guide for the sliding plate L, said sliding plate havinga back portion M and a base N bent at right angles to one another, saidbase having a slot 0 adapted to fit over the pin P secured to the base Cof the body A which acts as a stop for the sliding plate L, thuspreventing it from being moved too far either inward or outward. Oneedge of the base N may be turned over as indicated by Q acting as a holdso that the sliding plate may be readily pulled out.

R represents a strip of soft material such as felt which is secured tothe under surface of the base G of the body A, is then passed over theturned up portion 1) and attached to the upper surface of the swingingplate F thus making a neat and flexible surface.

-S is an eyelet secured to the upper edge of the back B whereby theshield may be readily placed or removed from beneath the door.

In practice the shield is inserted beneath the door T between the loweredge thereof and the sill U, and by pushing the back B toward the doorit will cause the swinging plate F to move downward against the actionof the spring G toward the bottom C, and as the spring G keeps theswinging plate F constantly in engagement with the door T, the openingbeneath said door will be closed which will prevent dust or a draftpassing through the space under the door. Should the body of the shieldbe too short for the door the sliding plate L may be drawn out thedesired distance which will prevent a portion of the dust anddraftentering the space between the door and sill. lVhen the slidingplate L is used it is found desirable to insert the shield far enough heneath the door so as to bring the back B in contact with the door.

In Fig. 4; I have shown a slightly modified form of my invention whichis preferably formed of heavy card board, having a back B, a bottom Cbent at right angles to the back and a swinging plate F bent back uponthe base C at some suitable angle so that when it is inserted beneaththe door said swinging plate will rest against the lower edge of saiddoor. In manufacturing the modified form it will be made of such lengthas to fit the widest doors and may then be cutupon any of the dottedlines (1, thus making it fit the door with which itis to be used.

In Figs. 5 and G is shown the form of my invention which I usuallyprefer, and which consists of the back B bot-tom C and the swingingplate F made of card board or the like. Vith the back is formed theledge B which is cut away at each end, thus serv ing as a hand held formanipulating the shield. This ledge may be bound with a metal strip B Inorder that the bottom and back may be rigidly held. at a proper angle toeach other, I provide a metal plate B which is glued, riveted orotherwise secured upon the inner surfaces of the bottom and back, asclearly shown in Fig. 6, and over this metal stay is a covering B ofcloth or paper. The swinging plate F has the straps F secured thereto,the inner ends of these straps being attached to the bottom C asindicated at C This arrangement limits the outward swinging movement ofthe plate I thus always holding the plate at its normal angle, fromwhich point it may be swung downward to another angle to adapt it to thespace beneath the door. If desired the outer surfaces of the plate,bottom and back may be covered with paper or other suitable materialthus giving the device any particular finish desired. The metal stay Bis preferably only the length of the ledge B thus leaving those portionsof the shield which project beyond the ledge capable of being cut by anordinary pair of shears or sharp knife, and in this way the shield maybe adapted to any width of door, varying from the length of the ledge tothe full length of the shield.

My improvement while especially adapt ed for use as a dust shield toclose the space beneath a door, is also well adapted for use uponwindows to prevent the same from rattling and to act as a weather stripin keeping out the cold air.

Of course I do not wish to be limited to the exact details ofconstruction here shown, as these ma y be varied within the limits ofthe appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is
